TO ALL WI-IOM IT MAY OONOERN:

Be it known that ALBERT M. lVlIITE, ofthe city, county, and State of NewYork, have invented a new and useful improvement in Brushes; and I dohereby declare that 4the following is a full, clear, andiexactdescription of the same, reference being had to the accompanyingdrawings, making a portion .of this specification, in. Which- Figure 1is a vertical section of a brush constructed according to my invention.

Figure 2 is a vertical section of the same, taken at right angles tofig. 1.

Figure 3 is a. partial horizontal section of the same, taken in the line:c x of figs. 1 and 2.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention may be considered usan improvement on'the invention setforth in Letters Patent of the United States fr improvements in themanufacture of brushes, granted to ALBERT M. WHITE, and bearing date the18th day of April, 1865, and its object is to ena-ble the said inventionto be more successfully applied in making brushes, the backs or stocksof which are formed ofivory or other substance of like hardness, ithaving been found by experiment that the excessive hardness of the ivoryprevents the ends of the staple-like Wires employed in securing thebristles or other equivalent material in their places from indentingthemselves into the sides of the holes or recesses provided for thereception of the said wires, as required in attaching the bristles ortheir equivalents to the stock or back of the brush, with the samefacility as when such stock or back is made of softer material.Tor'emedy this difficulty the present invention consists in theconstruction of the aforesaid holes with recessed or chambered bottomsor backs, whereby the staple-like wires, when forced into them, arecaused to bend' over and become firmly clinched, in such manner as tosecurely attach the bunches of bristles, or their equivalents, to theback or stock, however hard the material may be of which the latter iscomposed.

Tol enable others to understand the nature and construction of myinvention, I will proceed to describe it with reference to the drawings.l

The solid ivory stock or bach of the brush is shown at A, and hasdrilled or formed in its under side any required or suitable number ofholes, a, which do not extend quite through the aforesaid stock, and thebottoms of which are enlarged or chambered as indicated at a', the saidholes a being intended for the reception of the inner 'ends of thebunches B-of bristles. The bristles of which these bunches B arecomposed', are doubled inlthe usual manner', and through the loops thusformed are passed the staple-like wires b, which being done, the loopedends of the brushes B, With the staple-like Wires passed through them,as just described, are placed in the holes a, and are forced inwarduntil the ends of the wires b, striking the bottoms of the said holes,are bent over the ends of the bunches, as'shown more clearly in figs.and 3, and forced outward into the chambers a', and holding upon oragainst the sides of the said chambers, tightly and effectually securethe bunches B in the stock or back A. I

What I claim as my invention, and desire to secure by Letters Patent, is

The enlarged chambers aof the holes a, in combination-With thestaple-like Wires b, substantially as and ur ose s ecied. fm the? p p A.M. WHITE.
